APPARATUS FOR CLEANING WOOL.

SPECIFICATION forming part of Letters Patent No. 555,885, dated March 3, 1896.

Application filed March 28, 1894.

To all whom it may concern.-

Be it known that I, OSCAR REICHENBAOH, a subject of the Queen of Great Britain, residing at 3 Cromwell Crescent, South Kensington, London, in the county of Middlesex, England, have invented Improvements in Apparatus for Cleaning Wool, &c., of which the following is a specification.

My invention relates to improvements in apparatus for cleaning wool and textile products from grease and other foreign matters by the aid of bisulphide of carbon, (hereinafter designated C8 and has for its object to reduce the loss of CS by as far as possible preventing evaporation and transport of the fumes thereof by air in or from the apparatus in which the wool is treated, both during the process of subjecting the latter to the action of the solvent and afterward when washing it to free it of the solvent and grease and other foreign matter released thereby.

In order that my invention may be more fully understood and carried into practice, I will now proceed to describe the same with reference to the accompanying drawings, of which- Figure 1 is a side elevation; Fig. 2, a plan of the system of apparatus I propose using for the purposes of my invention. Fig. 3 is a side elevation of the shaft and a washingmachine; Fig. 3 a portion of the same, showing raised cross-partition; Fig. 4, a sectional plan on line 00 as, Fig. 3; Fig. 5, an end elevation of part of the shaft and washing-machine, and Fig. 6 an elevation of a modified form of shaft. Figs. 7 and 8 are detail views showing the connection between the valves in the feed-shaft and between them and the vapor-controlling valve, also showing the valve arrangement in the air-passage between the several wash-machines. Figs. 9 and 10 are front and side elevations, respectively, showing the Y-piece and its co-operating parts; and Fig. 11 is a sectional view on the line 11 11 of Fig. 9.

The shaft or conduit to into which the wool is fed is divided at its upper end into two or more passages Z) I), provided at their upper and lower ends with valves 0 d, so arranged that the upper valves cannot be opened without previously closing the lower ones and at the same time opening the valve device 6.

Serial No. 505,489. (No model.)

The valve device 6 is in a pipe or pipes 6' connecting the passages 12 with a pipe 2, Fig. 2, which leads to a scrubber orcondenser, (not shown,) so that any fumes or vapors which may pass off from the apparatus containing the CS and escape into the passages b will be drawn away through this valve 6 and pipe .2 for recovery. The wool is charged into one of the passages Z); the valves are then worked in the reverse order and the other passage, 1), filled, the wool, when the lower valves are opened, being precipitated onto a closed valve f, Fig. 1, in the shaft below the passages I) Z).

\Vhen a sufficient quantity of wool has collected in the shaft, the valve fis opened and the wool allowed to descend gradually into the CS contained in the hermetically-closed apparatus A, through which and the hermetically-closed washing-machines B O I) E it is then caused to travel.

The valves 0 of which there are two have V sectors a secured 011 one end of their spindles and the corner weight b on the opposite ends, which will support the valves either in their open or closed position as they are operated. The valve (Z is also provided with a sector 0 and counterweightj" for a similar purpose. With the sectors a and o sectors 011 the Y- piece g gear in such a manner that when this Y-piece is moved in one direction it first operates the valve (1, so that this closes one of the passages b and opens the other passage. At the same time it operates the denble valve c to open a vapor-escape from the passage Z) through the valvee and pipe 2, and then opens one of the valves 0, which governs the feed-inlet to the passage 1).

During the return stroke of the Y-piece the valve 0 which was previously opened is first closed. The valve (Z is then reversed, closing the bottom of the other passage, Z), and at the same time the double valve is 0perated to open a vapor-escape from this passage, and then the other valve, 0, is opened.

The valve device 6 consists of a casing which is divided into two compartments 1" i" by a partition through which are formed two openings j j". These are governed by the sector-plates 76' 10, secured to the spindle of the valve 61 in such a manner that when one of the openings is closed the other is opened, and

vice versa. The compartment 4; is divided vertically into two other compartments, each of which communicates through pipes c with the interior of one of the passages band with the compartment 11 through one of the openings jj. The compartment i is connected with the exhaust-pipe .2 leading to the scrubher.

The travel of the wool I effect by the aid of the following mechanism, reference being made particularly to Figs. 3 and 4: On a shaft 9, one end of which projects through one side of the machine and carries the driving-pulley h, are mounted the gear-wheels "6. These gear-wheels 2' actuate the wheels 7t, and these, by means of crank-pins, the con necting-rods Z. The connecting-rods Z impart an oscillating motion in the first and last part of their stroke anda back-and-forward movement in their intermediate parts to the side rods 1%. These side rods are connected by means of links m, Fig. 3, to the roller-axles n, which are first rotated, then moved back, and again rotated and then moved forward, carrying with them the roller and rollerframes j. The arms 0, keyed on the shafts n, will thus at first be lifted clear of the liquid, moved back horizontally, then into the liquid and moved forward.

During the rocking of the arms the frame carrying the rollers may, if found necessary, be automatically locked in its position and released when the back or forward motion is to commence by any suitable mechanism, the links during these portions of the stroke being prevented from moving vertically. The

. wool is carried over any cross-partitions p,

Figs. 1 and 3", by arms 0 and 0, Fig. 3, gearedsomewhat differently for this purpose, or by a band, and up the false inclined bottom 19 onto the endless band g. This band (1 runs on a roller on the shaft g and on a second roller, g, driven by the band q. and mounted to revolve in the liquid, and lifts the wool out of the liquid, and, carrying it between the roller on the shaft 9 and an idleroller 13 mounted above it in the sliding bearings, discharges it into'the chute 7 leading into the next machine and having its lower end sealed by the-liquid in said next machine.

Fig. 6 shows a shaft similarly constructed to the shaft shown in Fig. 5, but having valve 0 arranged to open inward, and the valve (1 and intermediate valves d of different construction.

The CS when it becomes saturated in the machine A to the desired extent is permitted to escape for treatment by the valve 8, fresh it may be allowed to pass from machinesA and B to the respective stills. The communication between these tanks and machines may be cut off at will. The air-valve 1 leading from the atmosphere in the machine E to the air-main 2, which leads to the scrubber or condenser, is kept open when the machines are at work. The valves 2 are in pipes which connect the pipe 2 with the lower portions of the machine's A B O D, and are simply for the purpose of exhausting any vapor which may be left in if the machines have been emptied for opening out. These cocks may be surrounded by a water-jacket.

The valve 2 regulates the admission of fresh water to machine E. The passages y convey the water from the machines E D D O O B.

00 00, Figs. 1 and 3 are self-acting valves and passages regulating and equalizing the pressures of the atmospheres in the different machines when the pressure in any tank falls below the pressure in the adjoining tanks or machines.

w represents a water tank or receptacle at the top of and surrounding the shaft or conduit a, and o is a bell-shaped cover adapted to be placed over the upper end of the shaft when the machine is not at work, closing the same and forming a water seal, by reason of its flange resting in the water-tank w.

\Vhat I claim is 1. The combination of a vesselhermetically closed to contain the solvent, avertically-disposed feed shaft or conduit through which the material to be treated is fed having its lower end dipping into and openingbelow the level of the solvent, valve devices which cut off free communication between the open air and the interior of the said vessel, and a valved pipe opening into the said conduit,

through which the air and vapors in the conduit may be drawn off, substantially as described.

2. In a machine of the characterdescribed, the combination of ahermetically-closed solvent tank or vessel, one or more hermeticallyclosed washing machines or vessels, liquidsealed connecting-passages between such vessels consisting of the chutes 1 leading from one machine or vessel to the next, and each having its end open and dipping beneath the liquid in the last said machine or vessel, and means for feeding the material to be treated through the said vessels, and from one vessel to the next, substantially as described.

3. In a machine for cleaning wool and the like, the combination of a series of washingmachines or apparatus, hermetically closed from each other and from the external air, a valved air-pipe opening into the last one of the said series of closed machines, and pressure-regulating air connections between the several machines, whereby air required in such machines will first enter the machine last in the series, and pass thence success 1o washing-machine of the series, and between the successive washing-machines, air-channels between the said machines, a valved airpassage between the last machine of the series and the open air, and means for supplying the said machines with suitable liquid, and for drawing OK the same, substantially as and for the purposes set forth.
